Good Eggs stores this product under refrigeration, and delivers it to you at ambient temperature- for the longest shelf life, refrigerate again when you receive it. Professional quality yeast, perfect for everyday baking. Part of its preference in the home bakery comes from its shelf life. Unlike compressed yeast, which must be used within a couple of weeks at most, active dry can keep for a very long time. While it keeps best under refrigeration, you can actually store dry active yeast at room temperature for several months before it loses potency. As far as taste goes, it imparts a bit of a sharper and more fermented flavor to your baked products than does compressed yeast. It does require a bit of preparation to activate properly. The best method for this is to sprinkle it on top of water heated to 105-115 degrees. Once the water shows some foam forming (usually about 5-10 minutes), the yeast is active for use.
